CD8A and neoplasm: In order to generate a fully autologous vToC, with tumor‐infiltrating immune cells, we processed the surgical sample of patient #14 by combining the EC isolation protocol from healthy tissue as described above (Figure 2A) with the isolation protocol of cancer cells, CAFs and CD8+ TILs from tumor tissue, which we previously described.[63] The four autologous cell populations were cultured in appropriate media and supports for few weeks (see Experimental Section) before seeding in the vToC.
